The Colossus has a symbiotic relationship with a tree growing in him anatomy, the roots are his veins, the leaves are his lungs.The benefit is mutual, since the tree is protected by a tough translucent sphere, and it stores the sun's rays, which provide energy to the colossus.He spends most of the time buried under the ground, exposing only the sphere.

Wooow, this thing is absoloutely beautiful, and I bet it'd be a great surprise in Rift to approach the sphere, only to have it tear from the ground and confront you.. It's an awesome creature, good luck iwth the competition!!!
